Designing Disordered Structures to Manipulate Antenna Radiation

We derive a simple and efficient method for designing wave--shaping materials composed of dipole scatterers. We apply our theory to design aperiodic metasurfaces that re-structure the radiation from a dipole emitter in many ways. Our proposed technique is relevant to designing metamaterials for a wide class of applications, and has the key benefit of including all interactions within the system of scatterers. Additionally, we develop a clear physical interpretation of the optimised structure, by extracting `eigen-polarizabilities’ of the system
